How accurate are they?

If it's like the TIGER city limit data, I say no.  (TIGER is radically
wrong about where city lines are, for example, Beaverton, according to
TIGER, has roughly five times the area and twice the population it does
in reality).

If it's like the EPA data, I say no.  The EPA data lists places that no
longer exist, and puts locations in the middle of streets, etc.
